Oxygen band company It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Hefei Oxygen band It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.
Hefei Oxygen band It is used for transportation, construction and other operating equipment. Incorrect operation and incorrect environment may affect the normal use of steel braided sandblasting pipe. What specific factors will affect the normal use of steel braided sand blasting pipe? The quality will definitely affect the use effect. The poor quality is actually related to the selected raw materials. Some raw materials are of high quality, and the quality of steel braided sandblasting pipes produced is also very good. However, if the steel braided sand blasting pipe is made of inferior plastic, the quality is very poor, which also affects the use effect. The use environment affects the use effect. Anti static steel braided sand blasting pipe is usually used in industry. Because these products are very common, the demand is also large. However, people do not pay attention to the use environment. If used in strong acid and alkali environment, steel braided sand blasting pipe will naturally corrode. Or if used in a relatively high temperature area, the steel braided sandblasting pipe may melt. Anti static steel braided sand blasting pipe will also affect the use effect. In the eyes of most users, the greater the degree, the better the nature. So if you choose a good one, users can use it with confidence. Understanding and avoiding the wrong use of high-pressure pipeline can reduce the possibility of high-pressure pipeline failure. The following brief introduction will help you. 1. Frequent and serious pressure shock: high-pressure pipeline burst is generally not caused by excessive static pressure, but is related to the severity and frequency of pressure shock. During the operation of construction machinery, the sudden increase or decrease of oil pressure in the high-pressure pipe will occur repeatedly, which will cause frequent pressure shocks to the oil pipe, leading to the aggravation of oil seal damage at various parts, blistering and cracking of rubber hose, and loosening and leakage of pipe joints. Therefore, during operation, the valve rod shall not be pulled too hard, but must be pulled gently. 2. The use temperature of oil is too high: during the operation of construction machinery, due to the power loss of the hydraulic system, the oil will rise, and the external temperature (especially in summer) will lead to a sharp rise in the oil temperature. wear-resisting Oxygen band company The higher the oil temperature is, the easier the rubber is to age, the worse the elasticity is, the lower the strength and sealing performance are, and the high-pressure pipe will burst rapidly. Therefore, when the temperature rise of the hydraulic system is too high or too fast during operation, the causes should be found out and eliminated in time. For summer operation, especially continuous operation, necessary cooling measures shall be taken.
Hefei Oxygen band It is a kind of hose that can be used for sand pumping and sand suction produced with high abrasion resistant rubber. It is often used in sand blasting industry, cement, steel, minerals and other industries, but it is mainly used in river dredging, slurry transportation in mines, sand digging and sand taking and other industries to transport sharp granular solids or solid-liquid mixtures. Its product structure is composed of high wear-resistant layer, reinforced water pipe layer, skeleton steel wire and outer rubber. Today, Myers will introduce the application field of wear-resistant sand absorption rubber pipe. When the wear-resistant sand suction rubber pipe is applied in the mine pit, it is necessary to set a floating boat equipped with a sand pump in the mine pit, and use the floating sand suction rubber pipe to connect with the sand pump. The floating boat will float up and down with the rise and fall of the water level. It is required that the pipe body has good flexibility and good tear resistance and bending resistance. The offshore pipeline is connected by non floating sand suction hose until the pulp transportation destination. The overall pipeline is divided into two parts, one for surface use and the other for onshore use. The main raw material of these two kinds of hoses is high abrasion and corrosion resistant rubber, and cord reinforcement layer and steel wire skeleton layer are added in the pipe wall to ensure the pressure resistance and tear resistance of the hose. The connection mode is vulcanized flange connection, that is, the flange and the hose are a whole, so there is no need to worry about the flange falling off. Floating sand suction hose used on the water surface. This kind of hose is required to float on the water surface. Due to the large drop of the mine (100 meters) and the long conveying distance Oxygen band company The hose shall have high pressure resistance, and the design pressure is 25 kg/cm2 according to the calculation. It should be considered that the floating ship will move up and down with the rise and fall of the water level and the wave will cause lateral displacement. Its internal structure is the same as the sand suction hose used offshore, except that a floating body is installed outside the hose.
Many people have never understood wear-resisting Oxygen band It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Oxygen band company Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.
wear-resisting Oxygen band It is a key component of any hydraulic system. When they fail, everything will stop. The preventive maintenance of the metal sandblasting hose is very important and needs to be checked regularly in order to find problems before starting. This may include checking hose caps and fittings, and looking for other signs of leaks and impending hose failure. The more strict the hose inspection process, the more reliable your equipment will be. 1. Benefits of preventive maintenance of metal sandblasting hoses: preventive maintenance of metal sandblasting hoses and equipment is always better than reactive maintenance. One reason is that it can make your equipment run efficiently by solving problems before they fail and have a significant negative impact on the system. Contrary to what many people think, preventive maintenance means reducing downtime due to unexpected component and system failures. Attention to maintenance can also extend the expected life of equipment, maximize its economic value, and minimize potential safety hazards to personnel. Finally, preventive maintenance can reduce maintenance costs and unnecessary equipment procurement. Not participating in regular preventive maintenance can be an expensive decision. 2. Maintenance time of metal sandblasting hose: Oxygen band company Part of the preventive maintenance program for solid metal sandblasting hoses includes periodic inspection of metal sandblasting hoses. Fixed equipment shall be inspected every three months. For mobile equipment, hose inspection shall be conducted every three months or every 400 to 600 hours, whichever comes first.
As wear-resisting Oxygen band As an important part of sand blasting machinery, its safety plays a vital role in the safety of equipment operation. The following will briefly analyze the precautions in the use of high-pressure sandblasting pipe: I. Pipe inner diameter: inner diameter of high-pressure sandblasting pipe. 2、 Attention shall be paid to the following items in the use and design of high-pressure sandblasting pipe: 1. The bending radius of high-pressure sandblasting pipe shall not be too small, and generally shall not be less than the value specified in the assembly technology of high-pressure sandblasting pipe. The joint between the high-pressure sandblasting pipe assembly and the pipe joint shall have a straight section, and its length shall not be less than twice the outer diameter of the pipe. 2. The length of high-pressure rubber hose assembly shall consider that the high-pressure rubber hose will shrink and deform after introducing pressure oil. Generally speaking, the shrinkage rate is 3~4 times of the pipe length. When installing the high-pressure rubber hose assembly, it is not allowed to bear tension. 3. During installation, the high-pressure sandblasting pipe assembly shall be free from torsional deformation. Oxygen band company The connecting shaft of shall be placed in the moving plane as far as possible to avoid damaging the high-pressure sandblasting pipe when both ends move with each other. 4. High pressure resistant sand blasting pipe shall avoid contact and friction with mechanical sharp corners to avoid damaging the pipe. Safety measures: to ensure the safe and reliable use of high-pressure sandblasting pipe assembly.
